Experimental study of dropwise condensation on plasma-ion implanted stainless steel tubes

Review of Micro–Nanoscale Surface Coatings Application for Sustaining Dropwise Condensation

“…Surface roughness and composition changes are also confirmed by [108] as the cause of DWC, instead of decreasing behavior of wettability, during their study of ion implantation of N + and Ar + on Al alloy. Kananeh et al [109] found a positive effect of steam pressure on DWC, and htc increased by 3.2 times for a N + ion-implanted SS surface was also reported in their study. Ion implantation for condensation has been studied broadly by Leipertz and Froba [49] and Guo et al [110], who stated that it is mechanically stable.…”

Review of vapor condensation heat and mass transfer in the presence of non-condensable gas

“…The larger contact angle between the droplets made it more difficult to form a combination, which made it more effective to form DWC. Then other researchers [63,64] started to investigate. With the deepening of study, researchers found that the surface of the ionic polymer tends to be hydrophobic or superhydrophobic, resulting in the growth of small droplets with an increased droplet contact angle, thus promoting droplet loss and DWC stability.…”

Nanotechnology for Advanced Nuclear Thermal-Hydraulics and Safety: Boiling and Condensation

“…Inorganic coatings were also examined. Some researchers have investigated dropwise condensation of diamond-like-coatings (DLCs) and ionimplanted coatings on aluminum and copper plates [83,110,111,112]. Koch et al [82] reported that the dropwise condensation heat transfer rate increased with an increase in the contact angle, as shown in Fig.…”
